SPECIFICATION forming partcf Letters Patent No. 603,346, dated May 3,1898.

Application iiled September 22,1896. Serial No. 606,658. (No model.)

To all whom t may concern,.-

Be it known that I, HARRY A. SEDGWICK, a citizen of the United States ofAmerica, residing at Athol, in thecounty ot Worcester and State ofMassachusetts, have invented new and-useful Improvements in Ball-Cocks,of which the following is aspecication.

This invention relates to ball-cocks, the object being to provide aball-cock of improved construction relative to means for governing theadmission of water thereto and the discharge of water therefrom; and theinvention consists in the peculiar construction and arrangement of theseveral structural elements of said ball-cock, all as hereinafter fullyset forth, and more particularly pointed out in the claims, Y

In the drawings forming part of this speciiication, Figure 1 is avertical sectional view of a ball-cock embodying my improvements, themain valve in this figure being shown closed and portions of thereceiving-tank to which the ball-cock kis attached being alsoillustrated in this ligure. y Fig. 2 is a similar view to Fig. 1, butshowing the said main valve open. Fig. 3 is a side elevation vof theball-cock, showing the controlling-valve and the barrel inclosing thesame in longitudinalv section. Fig. 4 is a side view of a portion of thebody of the cock and a longitudinal section of the controlling-valve andthe barrel thereof. Fig. 5 is a side elevation of the controlling-valve,the ball-rod-clamping devices thereon, and a portion of said rod. Fig.Gris a perspective view of the parts shown in Fig. 5. Fig. 7 is asectional view of lthe controlling-valve on line'7 7, Fig.` 5.

In the drawings, A indicates the body of the ball-cock, which bodycomprises integrally its main cylindrical portion the intake branch 2 ofthe cock, the barrel 31, in which the controlling-valve is located,connecting parts between said barrel and said main cylindrical portionin which are kwater-passages 7 and 8, a valve-seat 10, and a dischargeend 9. Into the upper end of said bod7 A is screwed a plug 14, on theinner under side of which isV a downwardly-proj ectin g part 26. Theinterior surface of said body is properly nished for the reception andproper movement of the :main valve 12, and near the lower end of saidbody and within said part thereof which rej nicates directly with theinterior of said body a little above said valve-seat 10, as shown inFigs. 1 and 2. Said water-passages 7 and 8 are formed through parts ofthe casting of said body, as illustrated, said vpassage 7 forming watercommunication between the upper side of the interior of said barrel 31and the portion of the interior of said body, just under said plug l-.Ltherein, and said passage 8 forming a like communication between thelower side of the interior of said barrel 31 and the portion of theinte-rior of the lower discharging end 4 of said body. Thesaid tubularintake 2 of said body A may have its extremity screwthreaded forA theconnection therewith of a water-supply pipe 32, or saidy pipe may besoldered thereto. A supporting-boss or bolster-block 5 is cast on theunder side of said intake branch 2, which provides convenient means forsecuring the ballcock ou the edge or other suitable part of a water-tank6, whichA receives its water-supply through said cock. Said Amain valve12 midway of its extremities than at the latter,

as shown, thus forming a chamber about the valve and having at its lowerend an invertedcup-shaped form, the `borders of which cup 30 areadaptedto enter said circular chamber 28 loosely, as shown, surrounding saidvalve-seat 10 when the said main valve occupies the downward'positionshown in Fig. 1. A packing 16, of disk form, is placed in the saidcup-like socket in the lower end of said Imain valve 12, which isadapted for action applied over and against the upper surfacev of saidpacking 15. It will be noted thatthe upper wall of said chamber has asupercial area greater than its lower wall and that, as

IOO

aforesaid, the borders of the inverted cup 30 on the lower end of valve12 enter the circular chamber 2S loosely. Thus with the parts inposition as shown in Fig. 2, in which water may flow into said chamberand water may escape freely from said space above the valvepiston, thepreponderance of pressure action is upward against the upper wall ofsaid chamber, and hence said main valve is raised by said preponderanceof pressure to the position shown in said figure to permit water to flowinto said tank, as hereinafter set forth.

A bolt 17, having a head on its lower end, as shown, is passed upwardlythrough said packing 1G, the body of said main valve 12, the packing 15thereon, and said washer 19, and a nut 1S securing said bolt and severalvalve parts firmly together.

A controlling-valve 13, so called because it controls the action of themain valve, has, as usual in silnilar Constructions, a mainwater-passage 21 transversely through it from side to side, and it alsocontains a second and smaller transverse water-passage 22 near saidpassage 21 and at right angles to the latter. Said controlling-valvecontains also a third water-passage 23, extending from the inner wall ofsaid passage 21 in a diagonal direction to the surface of said valve.The surface of said valve 13, at the outer end of said passage 23, maybe channeled, as at 27, Figs. (5 and 7, in order, as hereinafter setforth, to obtain a certain variable effect resulting from the flowing ofwater from passage 21 in valve 13 through said passage 23 into passage7, and thence into the valve-body above the main valve 12, whereby the frequencyof the action of the cock for admitting water to the tank G isregulated. Said controlling valve 13 is cast, preferably, with theserrated rosette 2O integral with its larger end. An eyebolt 33 isprovided with a thumb-nut 34. The shank of said bolt passes through saidrosette, and said nut is adapted to screw onto said shank after passingthe end of the ball-rod 25 through the eye of said bolt, therebyadjustably attaching the ball-float 2t to the controllingvalve.

The operation of the above-described improvement is as follows: Assumethat the controlling-valve 13 occupies the position shown in Fig. 2,which is the one which permits water to flow freely through the intake2, and thence through the passage 21 in said controlling-valve, into thelower part of the body A, and thence into the tank (5. During this timethe main valve is in the upward position. (Shown in said last-namedfigure.) The water thus supplied to said tank gradually rises, andthereby lifts the ball-float, and consequently turns saidcontrolling-valve in its inclosing barrel 31 until it is brought to theposition shown in Fig. 1. It will new be seen that the passage 23 insaid valve forms a water connection between the main passage 21 and thelower end of the passage 7, which forms communication between the upperinner side of said barrel 31 and the chamber in the body A above themain valve 12. Consequently water under pressure will flow into thechamber above the latter-named valve, thereby forcing the same downwardagainst the valve-seat 10, thereby stopping the flow of waterinto saidtank. The main valve is therefore now held against its said seat underthe full force of the supply-pressure. When the height of the water insaid tank becomes again lowered, the controlling-valve 13 turns slowlyuntil it again reaches the p0- sition shown in Fig. 2; but the mainvalve 12 remains shut or in the downward position (nearly to that shownin Fig. 1) until the rotary movement of valve 13, caused by outflowingwater, has brought the transverse passage 22 in said main valve to aposition whereby its opposite extremities register with the end ofpassages 7 and S, (see Fig. 2,) which extend from said barrel 31 to theinterior of body A above the main valve and to the discharge end et ofsaid body. Thus direct communication is formed between the upper end ofthe main-valve chamber and said outlet. This immediately relieves thepressure in the upper end of said chamber andiallows the main valvetorise or open, and as it moves upward it is stopped by the engagementof the upper end of bolt 17 with the projection 2G on the under side ofthe nut 14. The main valve 12 being down and closing against its seat10, as in Fig. 1, and the water in the tank 6 being at such a level, asthrough the ball-float and lever 25, brings the passage 21 in theturning plug 13 to the position shown in said last-named figure.Incoming water under pressure is supplied under said hat-brim packing onsaid main valve; but owing to a like pressure upon the upper end of saidmain valve, due to the connection by the water passages 7 and 23 betweenthe chamber above said main valve and passage 21 in said plug 13, thepressure above and below said hat-brim packing is equalized and the saidmain valve cannot yet be raised from its seat, for the reason that thechamber above said last-named valve is for the moment filled with water;but when the said water-level in the tank becomes lowered by drawingtherefrom and said plug-valve 13 becomes turned to the position shown inFig. 2 a continuous free water-passage is formed from said chamber abovevalve 12 to the lower discharging end 4 of the valve-case through theinterconnecting passages 7 and S in the Valve-case and the transversepassage 22 through said plug 13, whereby said chamber is free frompressure. New the pressure of incoming water from branch 2 through thepassage 21 in the turning plug acts to raise the main valve from itsseat, as shown in Fig. 2, whereby more water is supplied to said tank.3y the use of said rotary controlling-valve containing saidwater-passages other than the said main passage 21, acting with saidpassages 7 and 8, as set forth, the ball-cock can IOO IIO

be adjusted to work within -any reasonable be opened. Thus thewithin-described ball-- cock, adjustable to any rise and fall of waterwithin reasonable limits and ordinarily operating only about six timesdaily, presents great advantages as to durability over an ordinary onewhich operates about thirty times a day, both cocks acting under thesame conditions of use as to quantity of water drawn from the tank. Thelower end of the main valve is cupped, as shown, to receive thevalve-seat, the body A being recessed at 28 to receive the lower end ofthe main valve. Therefore when said valve descends it carries the headof said bolt 17 into the upper end 29 of chamber 4, which said head tsrather loosely at the lower end of the body A. This same movement of themain valve 12 carries the lower end 30 of said valve into said recess 28and against the water therein, which water escapes slowly around thesaid lower end 30 of the valve 12 and around the head of said bolt 17.Thus by the above-described construction a perfect dash-pot orwater-cushion is provided which compels the said main valve to be seatedslowly, thereby effectively preventing any water-hammer.

When it becomes desirable, for effecting repairs, to completely shut offthe water-supply from'the ball-cock independently of shutting off themain or street supply, the ballioat 24 may be swung to a verticalposition, thereby bringing the main water-passage 21 in thecontrolling-valve 13 at right angles to the water-supply through theintake 2 and shutting off the said supply. A stop-pin 35 is placed insaid valve 13, (see Figs. 1 and 4,) which may engage any convenientprojection on the barrel of the' valve 13, and thus serve to hold saidball-Heat in said upturned or vertical position while said repairs arebeing made.
